“Boats already at sea during this period should stay offshore in deep waters until further advised,” the Philippine Seismology Agency said, and asked those living near the coast of Surigao Del Sur and Davao Oriental provinces to “immediately evacuate” or “move farther inland”.
Raymark Gentallan, local police chief of the town of Hinatuan near the epicentre said power had been knocked out since the quake struck, but disaster response teams had yet to monitor any casualties or damage.
The first waves were expected between 10.37pm and midnight and were expected to last several hours.
A tsunami warning was also issued by the US tsunami warning system.
Meanwhile, Japanese broadcaster NHK said tsunami waves of up to a metre were expected to reach Japan’s southwestern coast around 30 minutes later – by 1.30am on Sunday.
